If you were going to London England....

[AlphaSigOU]

All these recommendations are good... but one thing I have to make sure I plan to visit is Freemason's Hall, the home of the United Grand Lodge of England. Yes, they do offer tours and if you're a Mason, they'll put you in contact with a nearby lodge so you can visit -- don't forget to wear coat and tie (dress is much more formal). Afterwards, they usually have a 'festive board' where dinner is served and beer and wine (and sometimes mixed drinks) as well (US Masonic lodges for the most part are dry.)
